Abstract

PROBLEM TO BE SOLVED: To contrive to improve the appearance of printed character rows up to the same degree in that of a single type address seal by narrowing distances between the character rows adjacent to back and forth in a combination seal, which can continuously seal and is incorporated as ink-impregnated seal and, at the same time, to reduce the production cost of the seal. SOLUTION: A print unit 13 consists of an ink impregnating body 15 having a self shape retention and a rubber print body 14 bonded to the under surface of the body 15, resulting in preventing the rubber print body 14 from sagging by its own weight. As a result, a structure for holding the peripheral edge of the under surface of the conventionally inevitable rubber print body, can be omitted. Further, the forward and backward surfaces of a pocket 19, in which the print unit 13 is installed, can be made thinner to the forming limit as a film-like wall 22. The left and right and top surfaces of the pocket 19 are surrounded in a U-shape by a thick-walled main frame wall 21. The printable longitudinal width of the rubber print body 14 is enlarged by the amount obtained by forming the film-like wall 22 thinner, resulting in narrowing the longitudinal distance between the printed character rows and allowing to improve the appearance of the character rows to the same order in that of the single type address seal.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combination mark in which a plurality of element stamps are connected and used, and more particularly, to a combination mark in which each element stamp is a permeation mark which can be continuously stamped. A character string such as an address, a name, a corporate name, and a telephone number is formed in each element stamp.

[0002]

2. Description of the Related Art This kind of combination mark is disclosed in Japanese Utility Model Application Laid-Open No. 56-1.
Nos. 71250, 58-168448, 5
It is known in, for example, Japanese Patent Application Laid-Open No. 9-82753. Each of the element stamps constituting the combination mark is composed of a square plate-shaped stamp main body and a rubber printed body fixed to the lower end surface thereof. A fitting projection is provided on one of the joining surfaces of the stamp main body, and the other joining surface is provided. Is provided with a fitting recess.

[0003]

The address stamp includes a combination stamp as described above, and a single address stamp in which character strings such as an address, a name, a company name, and a telephone number are formed on a single rubber print. There is. In the case of the combination mark, the ink impregnated on the stamp table is attached to the mark surface and transferred to the paper surface, so that the stamping operation is troublesome. To avoid such inconvenience, most of the stand-alone address stamps are configured as penetrating stamps that can be continuously stamped. In the case of the combination stamp, the stamping operation can be simplified by penetrating the individual element stamps. However, this has the following problems.

In the combination mark, a rubber print for printing a character string such as an address, a name, a corporate name, a telephone number, etc. has a peculiar shape in which the front and rear width is small and only the left and right lengths are extremely large. There is. In order to penetrate and print such a horizontally-long rubber print body, the rubber print body must be fixed and held in a flat posture without hanging down for each element stamp. For example, as used in the existing penetration mark, a receiving frame portion is formed so as to protrude from the lower surface of the opening of the rectangular frame-shaped holder, and the rubber printed body is assembled from the upper surface side of the opening of the holder, so that the lower peripheral edge of the rubber printed body is received. When supported by the part, the horizontally long rubber print body can be held without hanging down. However, when the receiving frame portion is provided on the holder, it is inevitable that the printable front and rear width of the rubber print body is reduced by the overhang dimension of the front and rear receiving frame portions. For this reason, when looking at the printed character strings, the front-to-back spacing of each character string becomes abnormally large, and the gap appears to be missing as compared with the case of printing with a single-type address stamp.

[0005] In order to reduce the space between adjacent character strings printed in each element stamp, the present applicant has studied a mode in which a rubber print body is held by a holder made of sheet metal. In this case, as shown in FIG. 10, a receiving frame portion 46 is provided only on the front and rear sides of the lower surface of the holder 45 and does not affect the adjacent spacing of the character strings.
Was held between left and right. A plurality of protrusions 49 are provided on the opposing surface of the support plate 47, and the protrusions 49 are digged in to prevent the rubber print body 48 from hanging down. Since the holder 45 and the support plate 47 are each formed of a thin stainless steel plate, the distance between adjacent character strings printed by each element stamp is reduced as compared with the case where the receiving frame portions are provided before and after the lower surface of the holder as described above. did it. The problem is that the number of components is increased by the amount of the pair of support plates 47 and the upper frame 50 that receives and holds the upper surface of the rubber print body 48.
A lot of labor is required for assembling the holder and the holder 45, and the total cost of the combination mark may be high.

SUMMARY OF THE INVENTION An object of the present invention is to form an individual element stamp as a penetrating mark so that a stamping operation can be performed continuously and quickly, while holding a horizontally long rubber printed body without hanging down. An object of the present invention is to provide a combination mark that can reduce the distance between adjacent character strings before and after and improve the appearance of a printed character string to the same degree as a stand-alone address mark. SUMMARY OF THE INVENTION It is an object of the present invention to provide a combination mark which simplifies the structure of a printing unit mounted on a stamp body, and which can reduce costs required for processing and assembling by reducing the number of components.

[0007]

According to the combination mark of the present invention, a printing structure and a connecting structure for joining adjacent element stamps 1 to 3 are provided for each of a plurality of element stamps 1 to 3. . The printing structure includes a plastic holder 12 having a pocket 19 opening downward and a printing unit 13 mounted and fixed in the pocket 19, and is configured as a penetrating mark capable of continuous printing. The left, right and upper sides of the pocket 19 are surrounded by a thick main frame wall 21 in a U-shape, and the front and rear of the pocket 19 are closed by a film-like wall 22. The rubber printing body 14 constituting the printing unit 13 is fixed to the lower surface of the ink impregnated body 15 having a self-retaining property, and is held by the ink impregnated body 15 so as not to hang down. Then, the printing unit 13 is mounted and fixed to the pocket 19 from the lower surface side.

More specifically, projections 2 for fixing and holding the printing unit 13 are provided at a plurality of locations on the inner wall surface before and after the pocket 19.

And a surface 32.

[0013]

Since the printing structure of each of the element stamps 1 to 3 includes the holder 12 having the pocket 19 and the printing unit 13 to be mounted in the pocket 19, the printing structure is permeated. Can be continuously printed by simply performing a stamping operation, and the stamping operation can be performed quickly and easily. The rubber printed body 14 is fixed to the lower surface of the ink impregnated body 15 having self-retaining property so that the ink impregnated body 15 prevents the rubber printed body 14 from hanging down. There is no need to provide a receiving structure. Therefore, pocket 19
The left, right, and upper surfaces of the pockets 19 that affect the adjacent distance of the character strings are secured by enclosing the holder 12 in a U-shape with a main frame wall 21 of a thick wall that does not affect the adjacent distance of the character strings. The front and rear can be formed by a thin film-like wall 22, and
The film-like wall 22 can be thinned to the molding limit. Therefore, according to the combination mark of the present invention, the printable front-rear width of the rubber print body 14 is increased by the amount that the film-like wall 22 can be formed thin, the front-rear interval of the printed character string is reduced, and the appearance of the character string is reduced. It can be improved to the same degree as a stand-alone address stamp.

A holder 12 having a printing structure made of plastic
And the printing unit 13 mounted in the pocket 19, so that the rubber printing body is supported by a sheet metalized holder and a support plate, and the rubber printing body is pressed and held by the upper frame. The number of components of the unit 13 is reduced, and the assembly of the printing structure can be completed with a minimum amount of labor for inserting and mounting the printing unit 13 in the pocket 19, so that the manufacturing cost of the combination mark can be reduced as a whole.

Projections 23 for fixing and holding the printing unit 13 are provided at a plurality of locations on the inner wall surface before and after the pocket 19, and at least the ink impregnated body 15 of the printing unit 13 is fixed and held by the projections 23 so as not to fall off. Then, in addition to the elasticity when the rubber print body 14 is fitted into the pocket 19, the elasticity and frictional resistance of the ink impregnated body 15 caused by the protrusion 23 biting into the ink impregnated body 15, the printing unit 13 is attached to the holder 12. On the other hand, the printing unit 13 can be more securely fixed and held, and can be easily assembled simply by pressing the printing unit 13 into the pocket 19. The protrusions 23 penetrating into the ink impregnated body 15 prevent the printing unit 13 from moving left and right and prevent the printing unit 13 from moving left and right during stamping, so that the printed character string is blurred or overlapped. Can also be prevented.

If each of the element stamps 1 to 3 includes a stamp body 6, a holder 12 detachably attached to the lower portion of the stamp body 6, and a printing unit 13 attached and fixed to a pocket 19, it is possible to display a house or telephone. When the element stamps 1 to 3 are updated in accordance with the change of the number, only the printing unit 13 or only the printing unit 13 and the holder 12 are partially updated, and the stamp body 6 can be reused as it is. Changes can be made at lower cost. In addition, by providing a combination mark using the stamp body 6 to a user who desires a combination mark of a conventional structure that has not been penetrated, this type of user can convert to a combination mark that has been penetrated. It also helps to reduce the cost burden when doing so.

The film-like wall 22 needs only to be thick enough to restrict the longitudinal movement of the rubber printing body 14 mounted in the pocket 19, and is as small as possible in order to reduce the longitudinal spacing of the printed character string. More preferred. However, when the holder 12 is molded by a normal injection molding method, if the thickness of the film-like wall 22 is less than 0.15 mm, it is difficult to form the film-like wall 22 even if the injection pressure of the molten resin is increased. In addition, the film-like wall cannot be formed stably. Conversely, the film-like wall 22
If the thickness of the rubber print exceeds 0.5 mm, the printable front and rear width of the rubber print cannot be sufficiently increased, and it is difficult to obtain the effect of reducing the front and rear space of the printed character string. Therefore, the thickness dimension of the film-like wall 22 is 0.15 to 0.5 mm.
It is preferable to set By the way, shut off the gate with the cavity filled with molten resin, and then
When the slide core is advanced into the cavity, the extremely thin film-like wall 22 can be reliably formed.

The holder 12 is made of a hard plastic such as ABS resin, polyamide resin, PC resin, PBT resin, or a polymer alloy thereof, for example, a polymer alloy of ABS resin and polyamide resin, a polymer alloy of PC resin and PBT resin. The ink impregnated body 15 is preferably formed of a rigid foamed plastic material such as polyvinyl formal.

The combination mark includes a plurality of element stamps 1-3.
Are used in close and forward bonding. For this reason, if the ink that oozes out of the rubber print body 14 adheres to the joint surface of the adjacent holder 12 at the time of stamping or the like, the ink moves to the stamp body 6 by capillary action, and stains the stamp body 6. In order to prevent such diffusion of the ink, an anti-soiling groove 30 is provided in the upper part of the front and rear surfaces of the holder 12 so that the groove 30 can block the ink from rising.
